HERMAN SAUTER, OF CHICAGO, ILLINOIS, ASSIGNOR TO LATHAM AUTOMATIC REGISTERING COMPANY, OF CHICAGO, ILLINOIS, A GGRPORATION OF ILLI- NOISL REGISTERING-EDGE.

Application filed July 12, 1919.

To all whom it may concern:

lie it known that Humans Sau'rnn, av citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Registering-liooks, of which the following is a specification.

liiy invention relates to what are known in the printers art register hooks, which are devices having base adapted to be locked in the chase 0i a printing form and equipped with a hook or engaging member adapted to interlock with the edge oi a plateto hold it in the form for printing. The objectof my invention is to provide a simple and strong device oi this character in which the hook member has an adjustable and swiveled support in. the base. to the end that the plate may be placed angularly with respect to the if desired, or that it may adjust itself to make contact with the edge of a plate on which the type characters or illustration thereon do not lie square with the edges of the plate. My invention con sists in the iorm.v arrangement and organization of the parts oi the novel register hook hereina ter described and which I have invent-ed and designed with the above object in viei the essential lements thereof being more particularly pointed out in the appended claims defining my invent-ion.

In the accompanying drawing forming part of this specification, Figure 1 is a plan view of a portion of a printers form showing the manner in which the hook used; Fi g. 2 is a perspective ot a complete base and hook; Fig. 3 is a perspective of one oi the two members of the sliding block in which the hook proper is mounted; Fig. i is a longitudinal vertical section of the device, showing a fragment of a plate with which it is adapted to cooperate; and F 5 is a rear view of the device.

The same reference characters in dicnte the same parts in all the figures of the drawing.

My invention is more particularly designed to be used with and as part oi a plate-mounting system in which the printing plates are beveled or undercut in a well known manner around their margin in order to adapt them to cooperate *ith hooks adjustably mounted on sliding blocks arranged in bases which are spaced in the form by means of plain bases or blocks of various standard dimensions. Briefly describing a Specification of Letters Patent.

ingly mounted. the hook members being ad- 6o justable in the bases 3 by the actuation of screws 5. Bases of varyingnumbers of ems are used, and also spacing blocks oi? various thickness to partially till the spaces oi the siotted block, and serve as abut-ments or the screws to bear upon, as may be needed to. make up a particular form. These hooks -.l, and also the swiveled hooks to which my present invention relates, are spaced and arranged according to the requirements of the particular case, six hooks being ordinarily used to secure each plate, one at each end (it the plate be oblong in shape) 31nd two on each side.

The slotted base in which my novel swiveled hook is mounted may be the same as the base 3 heretofore used with the hooks 4 above mentioned, and consists of a metal block 6 (see Figs. 2 to 5, inclusive) having rectangular faces, and channeled or grooved to form a slideway for the reception of the two-part sliding block 7*, 7 The block is divided on a plane lying transversely of the direction of movement of the block in the slideway, and its parts are firmly secured together by suitable means 8, as by screws or by rivets, four being employed for the purpose in the present instance. A longitudinal screw-threaded bore 9, engaged by the locking screw 10 corresponding to the screws 5 before mentioned, is formed in the block, and by turning the slotted head of the screw with a suitable implement pro vided for the purpose, the swiveled hook, which will next be described, can be forced into secure engagement with the plate which it is designed to secure.

The hook 11 (see Fig. t) has an upper flat portion 12 formed with a beveled overhanging engaging face 13 arranged to engage the beveled or undercut recess of the plate 14, and a depending short pivot 15 which is peripherally flanged or headed at its bottom. The block members 7 and 8 are formed with a pivot bearing adapted to receive the headed pivot of the hook, onehali the bearing being formed in each memher, so that the parts may be readily assembled and the block members secured together.

It will be seen from the description above given that my screw swiveled register hook is simple and extremely sturdy in construction and that it is admirably adapted to sustain long continued hard service.

I claim:

1. A device of the character described comprising a base member formed with a slideqvay, a separable divided block in said slide-way having its members formed with a longitudinal screw threaded bore, said block having a pivot bearing formed partly in each member of the block, a hook having a headed pivot engaging said bearing, and a locking screw engaging said bore.

2. A device of the character described comprising a base member formed with a slide-way a block consisting of two separable members arranged in said slide way and formed with a longitudinal bore, said block having a pivot bearing formed one-half in each of said members, a hook having a headed pivot engaging said bearing, and a locking screw engaging said bore.

3. A device of the character described comprising a base member iormed w1tl1 a slide-way, a block consisting of two members divided on a transverse line arranged in said slide-way and formed with a. longitudinal bore said block having a pivot hearing formed one-half in each of said members, a hook having a headed pivot engaging said bearing, and a locking screw engagin 1 said bore. 7

4. A device of the character described comprising a base member formed with a slide-way, a block consisting of two members divided on a plane at right angles to said slide-way and formed with a longitudi nal bore, said block having a pivot bearing formed one-half in each of said members, a hook having a headed pivot engaging said bearing, a locking screw engaging said here. and a series of rivets arranged parallel with said locking screw and arranged to secure said block members together.
